Colorado Antimicrobial Stewardship Endeavor (CASE)

CASE banner

About CASE: In August 2021, the Colorado Department of Public Health and Environment (CDPHE) partnered with Children’s Hospital Colorado to start the Colorado Antimicrobial Stewardship Endeavor (CASE). CASE includes physicians, pharmacists, and epidemiologists who provide mentorship and resources to Colorado hospitals that may be new to antibiotic stewardship. Antibiotic stewardship is the effort to measure and improve how antibiotics are prescribed by clinicians and used by patients. Improving antibiotic prescribing and use is critical to effectively treat infections, protect patients from harms caused by unnecessary antibiotic use, and combat antibiotic resistance. Learn more on the antimicrobial stewardship main page

Through a series of workshops and one-on-one consultations, CASE will support hospital antibiotic stewardship programs to:

  • Create evidence-based actions to improve antibiotic stewardship. 
  • Develop procedures to track and monitor antibiotic use and reporting.
  • Extend antibiotic stewardship activities to pediatric patients.
  • Develop programs that meet state and national standards and CDC’s Core Elements of Antibiotic Stewardship.
  • Interact with antimicrobial steward peers statewide.
  • Request one-on-one consultations from the CASE team.

CASE also seeks to provide resources such as treatment guidelines, support for reporting antibiotic use to the National Healthcare Safety Network (NHSN), and links to evidence-based guidelines and tools.

(New!) Firstline app: Keeping Colorado Healthy, One Antibiotic Choice at a Time

Antimicrobial stewardship is one of the best tools we have to fight back against antimicrobial resistance. While there are multiple guidelines for common infectious processes, applying them at the local level can be a time-consuming challenge. Children’s Hospital Colorado and Denver Health have partnered with Firstline to create a mobile app to change that. 

advertisement for children's hospital antibiotic app

Firstline houses clinical pathways from Children’s and Denver health, along with antimicrobial dosing information, pathogen information, infection prevention information, and more. It is intended for use in all clinical settings. The app is free to download, and is available on iOS and Android devices, as well as a web-based format. CDPHE supports the Firstline app in an effort to provide antimicrobial stewardship treatment guidelines and resources across healthcare settings.

No matter your specialty or practice, we are all stewards. We can all work together in keeping Colorado healthy, one antibiotic choice at a time.

Use the QR code above to find our app. Once downloaded, you can set your location to Denver Health and/or Children’s Hospital Colorado to access all of our materials. Once in the app, clicking on the FirstLine logo in the top left corner will allow you to toggle between locations to access adult vs pediatric guidance. Contact cdphe_hai_ar@state.co.us for more information or feedback!


(New!) The CASE Collective: a peer-to-peer series for critical access and community hospitals! 

We have expanded CASE in partnership with the Office of Rural Health to offer an antimicrobial stewardship series focused on critical access and community hospitals!

We encourage ongoing participation in CASE for workshops, office hours, and consultations. The goal of the CASE collective is to promote outreach and facilitate discussion among antimicrobial stewards at smaller or resource-limited settings across the state.

We invite you to join four virtual interactive calls with peer facilities and the interdisciplinary CASE team from August 2023 to May 2024. Participation is voluntary and at no-cost. Consultations and additional support are available through participation in CASE. Register for the CASE collective using the button below!
